<div><p>The <span class="bold">System</span> tab provides information about the system on which the JVM is running, performance attributes of the JVM, and a list of system properties.</p>
<p><span class="bold">Server Information</span></p>
<p>The <span class="bold">Server Information</span> panel at the top of the <span class="bold">System</span> tab contains a list of categories with values for the server on which the JVM is running. This information is useful for debugging development and runtime problems of the application, and for filing support requests.</p>
<p>This is general system information that you cannot change.</p>
<p><span class="bold">JVM Statistics</span></p>
<p>The <span class="bold">JVM Statistics</span> panel contains the current values for key performance attributes of the JVM. By default, the following attributes are displayed in the table:</p>
<ul style="list-style-type: disc;"><li><p>Currently Loaded Class Count</p>
</li>
<li><p>Uptime</p>
</li>
</ul>
<p>To add an attribute to the table, click the <span class="bold">Add attributes</span> button in the top right corner of the <span class="bold">JVM Statistics</span> panel. To remove an attribute, right-click it in the table and select <span class="bold">Delete</span>.</p>
<p>By right-clicking an attribute, you can change its update interval, units, and for some attributes it is possible to set the value.</p>
<p><span class="bold">System Properties</span></p>
<p>The <span class="bold">System Properties</span> panel contains a table with keys and values of all the properties invoked with the JVM. To filter the properties, select the filter column (Key or Value) and specify the filter string in the text field above the table.</p>
<p>This is general system information that you cannot change.</p>
